2021 Acura TLX A-Spec Long-Term Update | Infotainment system hits a pothole

The first few thousand miles of motoring in our 2021 Acura TLX A-Spec long-term test car were problem-free, but that changed after we took it on a spirited drive through the winding hills of southern Indiana. You can read about how it handled a full day of thrashing here, but this story will focus on the dead infotainment system previewed in the headline. About halfway through the twisty route, every sizable pothole or big bump in the road would cause the infotainment system to black out. A message would appear declaring “MOST NET LOSS,” and it would quickly dip to black after that. The next big pothole would cause it to flicker back on, but it never remained on for any long periods of time after this. In addition to the screen loss, the speakers would make some rather disturbing crackling noises. This continued throughout the day and for several days beyond that. If the roads I was driving on were flat or devoid of major problems, the infotainment system would generally be fine. It took a major jostling of the carÂ’s bones to cause it to act up, but Michigan provided enough of those to make the problem exceedingly annoying in a hurry. So, to the dealership it went. 2021 Acura TLX A-Spec View 51 Photos After the local dealer looked it over, they said there was a TSB out for this issue, and that theyÂ’ve seen it pop up on other RDXs and TLXs already. Turns out, there are a number of wire connectors between the infotainment system and wiring harness that are causing the problems and coming loose. The fix? Newly designed connectors from Acura, plus the wiring harness is ever so slightly freed up to allow for a bit of movement from violent impacts. Doing this (plus using the stronger new connectors) should ensure that the stress on these connectors is never so great as to cause issues again.  The job was completed under warranty and took a full day from diagnosis to the return of the car. WeÂ’ve put several hundred miles on the car since the fix, and theyÂ’ve been completely trouble-free — it sure was nice to listen to AcuraÂ’s excellent ELS audio system again. That said, this issue is one weÂ’ll follow closely to see if AcuraÂ’s fix truly is a long-term solution. WeÂ’ll have a deeper dive on how AcuraÂ’s TouchPad infotainment system works (now that itÂ’s actually working again) soon, so watch out for that update in the near future.

Acura claims MDX is best-selling luxury 3-row ever

Business for Acura has been in a weird place, recently, and the company's latest car launches have been especially rocky. For example, the ILX Hybrid was recently discontinued after just two model years with only about 2,660 sold in that time. The company also delayed the launch of its new TLX by a few months until later this summer. However, despite its issues with sedans, the automaker's utility-vehicle business in absolutely booming. In fact, it now claims that the MDX is the best-selling three-row, luxury SUV, ever.
The MDX is already leading its class this year with 30,664 units sold through June 2014, up 68.4 percent compared 2013. Also, in five of the last six months of reported sales, Acura has posted gains. It appears that the company's utility lineup is really pushing it along.
To take the bestseller ever crown, Acura claims that through its three generations, the MDX has sold a cumulative 692,710 units. The premium model has also been at the top of the annual sales rankings for three-row luxury crossovers every year since 2002. The company believes that its nearest competitor is the Lincoln Navigator with an estimated 420,000 lifetime sales, and even arguably more comparable vehicles like the BMW X5 and Mercedes-Benz M-Class only have 350,000 or fewer sales under their belts. Of course, it probably doesn't hurt that the MDX has one of the lower starting prices in its class.

Acura's GM-based electric crossover may be called ADX

Acura's version of Honda's General Motors-based electric crossover will inaugurate the ADX nameplate, according to a recent report. While nothing is official, the United States Patent and Trademark Office recently granted the Japanese company the rights to the name. Spotted by Car & Driver, the trademark application was filed by Honda on December 22, 2021, and approved three days later. Nothing suggests it's for a Honda, but a model called ADX would slot neatly into the Acura range, which also includes the MDX and the RDX. The filing asks more questions than it answers. What's an Acura ADX? One possibility is that the nameplate might appear on Acura's version of the Honda Prologue, which is due out for the 2024 model year. It will be based on a GM-designed platform, and it will be powered by the same Ultium battery technology found under the Cadillac Lyriq, among other EVs. We know it will spawn an Acura, too. It's important to note that nothing in the filing mentions an electric powertrain. Acura's range only includes two crossovers, which is far below the industry average (Lexus has five crossovers and SUVs; even Lincoln has four) so the ADX name could end up on a non-electric addition to the range. The line-up could grow in a number of directions and many of its dealers are asking for bigger and small people-movers. As we've said before, a patent or a trademark filing is not a guarantee that a feature or a nameplate will see the light that awaits at the end of a production line. Carmakers routinely protect their intellectual property to ensure that it doesn't end up in the hands of a rival. Although there's no such thing as an Acura ADX — at least not yet — the name falls in line with the company's naming system. Imagine the confusion that would ensue if, say, Lexus released a crossover called ADX that was aimed directly at the 355-horsepower Acura MDX Type S. Acura hasn't commented on the report, and it hasn't revealed what its Honda and General Motors-derived model will be called. Related video:
